<P CLASS=para>
Now that you know about the different classes necessary to print, let's 
put it all together. Printing takes four steps: 

<P>
<OL CLASS=orderedlist>
<li CLASS=listitem>Get the <tt CLASS=literal>PrintJob</tt>: 

<DIV CLASS=screen>
<P>
<PRE>
PrintJob pjob = getToolkit().getPrintJob(this, "Job Title", (Properties)null);
</PRE>
</DIV>

<P>
<li CLASS=listitem>Get the graphics context from the <tt CLASS=literal>PrintJob</tt>: 

<DIV CLASS=screen>
<P>
<PRE>
Graphics pg = pjob.getGraphics();
</PRE>
</DIV>

<P>
<li CLASS=listitem>Print by calling <tt CLASS=literal>printAll()</tt> 
or <tt CLASS=literal>print()</tt>. When this method 
returns, you can call <tt CLASS=literal>dispose()</tt> 
to send the page to the printer: 

<DIV CLASS=screen>
<P>
<PRE>
printAll(pg);
pg.dispose(); // This is like sending a form feed
</PRE>
</DIV>

<P>
<li CLASS=listitem>Clean up after yourself: 

<DIV CLASS=screen>
<P>
<PRE>
pjob.end();
</PRE>
</DIV>

<P>
</OL>
<P CLASS=para>
The following code summarizes how to print: 

<DIV CLASS=screen>
<P>
<PRE>
// Java 1.1 only
PrintJob pjob = getToolkit().getPrintJob(this, "Print?", (Properties)null);
if (pjob != null) {
        Graphics pg = pjob.getGraphics();
        if (pg != null) {
            printAll(pg);
            pg.dispose();
        }
    pjob.end();
}
</PRE>
</DIV>

<P CLASS=para>
This code prints the current component: what you get from the printer should 
be a reasonable rendition of what you see on the screen. Note that we didn't 
need to modify <tt CLASS=literal>paint()</tt> at all. 
That should always be the case if you want your printer output to look 
like your onscreen component.
